GAUGE WHEEL FR PLows Filed Nov. 12, 1928 I rml Patented Jan. 26, 1932UNITED STATES PATENT OFFICE CARL G. STRANDLUND, OF MOLINEKILLINOIS,ASSIGNOR`TO DERE &; COMPANY, OF MOLINE, ILLINOIS, A CORPORATION OFILLINOIS GAUGE WHEEL ron PLows Application filed November 12, 1928.Serial No'. 318,631.

'5 and depth regulating connections of the excessive strains to whichthey are subjected in plows having the common form of gauge wheellocated behind the plow and secured to the beam in a trailing position.I accomplish this object as illustrated in the drawings and ashereinafter described. TWhat I regard as new is set forth in the claims.

My invention consists in providing a plow with a gauge wheel adapted tobe attached to the plow standard so as to run on the land opposite themold board and at a distance from the landslide that may be varied tosuit the condition of the soil. The gauge wheel may also be adjustedvertically withY reference to the plow standard to gauge the depth ofplowing.

ln some soils the furrow wall tends to break away or crumble, and whileit is desirable to locate the gauge wheel close to the furrow wall, thistendency of the soil to break away frequently makes it necessary to setthe gauge wheel far enough away from it to avoid breaking it down.Furthermore, the common practice has been to securethe gauge wheel tothe plow standard by a rearwardly extending connection, so that thegauge wheel trails behind the plow, notwithstanding the fact that thisis objectionable because it imposes undue strain on the usual liftingand depth regulating connections with which gang plows are generallyequipped. It also imposes more strain on the plow beam and makes gaugingless accurate than where the gauge wheel is located opposite thelandside, i. e. at a point lying between the transverse vertical planesof Vthe plow body, asis the case in my improved construction.

The nature of my improvements will be readily understood from thefollowing description thereof in connection with the drawings, in which-Y Fig. 1 is a plan view of the rear plow body of a gang plow showing myimproved gauge wheel attached thereto in close proximity to the furrowwall;

Fig. 2 is a similar view showing the furrow wheel set at a considerabledistance from the furrow wall;

3 is an enlarged detail, being a vertical cross-section on lines 3 3 ofFigs. 1 and l; and

Fig. l is a partial longitudinal vertical section on line #fi-4l of Fig.1.

It will be understood that while in the drawings l have illustrated onlya single plow body with a portion of its beam, the illustrations are tobe considered as representing part of a plow of any suitable type, suchas a gang plow provided with the usual lifting and depth regulatingappliances, or a two-way plow, such as that shown and described in mypending application, Serial No. 260,872, filed March 12, 1928.

Referring to the drawings,-5 indicates a mold board plow having a beam 6and landside 7. rlhe rear portion of the beam, as usual, is curveddownwardly to form a standard 3 to which the plow body is attached inany suitable way.

"he gauge wheel is indicated as an entirety by the reference numeral 9.It is preferably of the disc type and is provided with a peripheralflange 10 that extends laterally at one side of the radial portion ofthe wheel, as best shown in full lines inFig. 3. In other words, thegauge wheel is in the form of a disc having a peripheral flange at oneside thereof that extends parallel with its axis vand constitutes thetread or rim portion of the wheel.

The hub of the wheel is composed of two similar members 11, 12 eachcomprising a sleeve portion 13 and an annular radial "such'sleeve Thebearing 25 -is provided with so that a single set of rivets secures bothhub portions in position on the wheel.

The inner surfaces of the sleeves 13 are preferably conical with theirgreatest diameter at their outer ends, and constitute the bearingsurfaces on which the wheel is axially supported.

A. bracket 17 having a flattened surface 18 at its upper endserves asmeans foi-,rotatably supporting'th'e wheel 9and attaching fitto' VEheflattened portion 18 is adapted to bear against the standard 8V the plowstandard 8.

and to be adjust-ably secured thereto by clamping bolts 19. boltsthatembrace the standard 8 andpart 18 of the bracket 17 and are securedbylnuts 20. Preferably a scraper 21 is connected to the arms ofthe upperbolt 19,'V and is Yheld in place'by the nuts 2O thereon, as shown inFigs. 1 and 3. This scraper extends over the tread" portion 10 of thegauge wheel and serves to remove soil therefrom as the wheel rotates. Y

At its lower end thebracket-17 is provided with a conical bearing 22 atthe base of which is a circular flange 23', thus providing a pocket toreceive the outer margin of the sleeve portion -13 of the hub portion11, when the. parts are arranged as shown'in Fig.- 3, or the. outermargin of the opposite-sleeve-13, whenthe gauge wheellis inits reverseposition indicated by dotted lines 'in-saidlfigure. A bolt 24 extendsthrough the bearing 22, and through the sleeves- 13,- and uponthe outerend of this bolt is mounted a detached bearing 25 similar in shape tothe bearing-22r The bearing 25 is adapted tot-in the outer sleeve 13,and-it is provided with a marginal flange 26 that overlies the outermargin' of a pocket 27 at its outerv end which receives the 'head22S-ofthe bolt 24, andV anut 29 is Vscrewedupon the inner end of saidbolt to hold'ther two ,bearings- 22, v25 together and provide for theiradjustment with reference to each other and to the sl'eeves`13.l

It will be seenfromvthe foregoing description that the gauge wheel? isprovided with t`wo alined hub members that extend'in opposite directionsfrom the radial'web 'portion 16 thereof, one of whichlies underv thetread of the wheel while the other projects outwardly beyond-such tread.Either of: these `hub portions maybe mountedupon the bearing 22 ofthebracket 17 to adj ustthe position of the tread portion 10 toward or fromthe plow standard 8,-thereby locating such tread portioneither closetothe standard or at a ldistance therefrom equal to the width` of the 60tread-portion, Aas clearly appears from Figs. 1,2: and 3. vWhere the hubmember 11 is mounted on the bearing 22y the tread'portion 1Q extendstoward the standard and lies in close proximity thereto, whereas byreversing the gauge wheel( and mounting the hub por- ThesearepreferablysU.

by the dotted lines in Fig. 3. In either case T0 the gauge wheel isrotatably supported by the two bearings 22, 25, and is-held in plaeefbythe bolt 24.

It will be understood thatthe dotted line position ofthe"gauge'fwheelisusedwhere 'the 75 soil'is of'suchl'cha'racter' that the furrow walltends to break away, whereas the full line positionis Y'used where thesoil is irm and there is. little if any-such tendency.

Location of the gauge wheel close to the landsi'de` makes-fori accurategauging, because thegauge wheel follows'the contourvoffthe groundadjacent to ltheplow",` and this Iresult is lalso promotedbysecuring-the gaugewheel totheiplow-'standard soth'at itlies between 85the transverse vertical planesuof' the plow body.l A furtheradvantage'of thus mounting the gauge wheel isthat'rit relieves vthestrain onthe lifting 'and depth reg-ulatingconnections ofithe plow, and,in the case' of atwo- 90 wayrplow, such as thatshownin my sadapplication Serial No.- 260,872, when-theplow is adjusted at itsfront-rendit turns about the gauge-wheel and less strain is Vthrownl onthe beam; The gauge wheelimaycreadilyfbe-'95 adjusted vertically. alongYthe ploW standard by` loosening theclampingsbolts 19.
